我们报告了我们在生产高效钠钙玻璃/Mo/Cu(In，Ga)Se2(CIGS)/CDS/i-ZnO/ZnO：Al/MgF2太阳能电池的基准工艺质量方面取得的进展。平均性能水平的提高使我们能够达到高达19.3%的转换效率(内部测量)。新的质量倡议使用过程控制、光学和电气建模以及对所有过程步骤的关键修订，作为实现19%效率水平的工具。我们的实验表明，效率为h19%的CIGS太阳电池的成分工艺窗口很宽。相应地，我们认为在以下组成工艺窗口中可获得19.0-19.5%的效率：0.69 GB Cu/(GaIn)GB0.98和0.21 GB Ga/(GaIn)GB0.38。此外，我们的结果表明，大的CIGS颗粒并不是高达19%的效率所必需的。这些发现，以及部分缺乏将我们进展的某些方面与实验参数相关联的能力，使我们得出结论，仍有一些重要的过程变量尚未发现。根据这一结论和对现有数据的评估，我们推断CIGS太阳能电池的效率有可能提高20%以上。版权所有#2007 John Wiley&Sons，Ltd.
We report on the progress that we have made in the quality of our baseline process for the production of high efficiency soda lime glass/Mo/Cu(In,Ga)Se2 (CIGS)/CdS/i-ZnO/ ZnO:Al/MgF2 solar cells. The enhancement of the average performance level has enabled us to reach conversion efficiencies of up to 19 3% (internal measurement). The new quality initiative uses process control, optical and electrical modelling, and the critical revision of all process steps as tools for the attainment of the 19% efficiency level. Our experiments show that the compositional process window for CIGS solar cells that have an efficiency of h 19% is very wide. Accordingly, we suggest that an efficiency of 19 0–19 5% is achievable in the following compositional process windows: 0 69£Cu/(GaR In)£ 0 98 and 0 21£Ga/(GaR In)£ 0 38. In addition, our results show that large CIGS grains are not a necessary requirement for high efficiencies up to 19%. These findings and the partly lacking ability to correlate certain aspects of our progress with experimental parameters lead us to the conclusion that there are still some important process variables undiscovered. From this conclusion and from the evaluation of the available data we infer that there is a potential for the enhancement of CIGS solar cell efficiencies beyond 20%.
